Section 2 Preparation
e) Finger tighten the nut. If desired, tighten the nut an additional 1/2 turn using a
wrench.
5. Loosen the nut (but do not remove) to the Solvent Select Valve Port “TO TORRENT
B LEVEL”.
6. Following step 4 above, connect the air supply from the B LEVEL on the Torrent to
the Solvent Select Valve “TO TORRENT B LEVEL”.
2.9 Connect Solvent Lines
CAUTION
To prevent damage or premature wear to the pump and internal valves, clean solvent should
be used. The solvent should not contain any dissolved solids. In addition, the B solvent pump
on the Torrent and both Solvent A and Solvent B pumps on the Torrent AQ are not
compatible with alkanes such as hexane due to lack of lubricity.
CAUTION
If solvent containers are reused, particulate matter can accumulate in the container.
Containers should be thoroughly cleaned before each refill. Failure to clean the containers
may result in damage to the solvent selection valve and internal components.
Note
The Torrent is shipped with protective caps on the solvent fittings. Remove these caps as you
connect the solvent lines. The internal solvent lines contain isopropyl alcohol, some of which
may drain when the caps are removed.
The Torrent may receive solvent from:
• User-supplied solvent containers at atmospheric pressure
• Pressurized or gravity-fed solvent delivery lines in the laboratory.
Refer to the appropriate installation section (2.9.1 through 2.9.2) according to your
solvent source.
2.9.1 Solvent Containers at Atmospheric Pressure
The Torrent can form a binary gradient from two solvents, A and B. These solvents
connect to the left side panel of the Torrent or Torrent AQ with optional Solvent Select
Valve allows for a binary gradient between one A solvent and either of two different B
solvents or liquid sample.
1. Locate the Solvent A inlet line. This assembly consists of two tubes fastened
together—a solvent line and a smaller diameter air line to measure the solvent
level.
2. Connect the large fitting to the Torrent’s A INLET port:
a. Position the end with the threaded fitting near the port.
b. Rotate the fitting until the inlet line is routed the desired direction.
c. Finger-tighten the pre-swaged fitting to the port.
d. Use a wrench to tighten the fitting an additional

turn.
3. Connect the air line to the A LEVEL port (refer to Figure 2-1):
